Valve Installation

If you install the valve yourself, refer to the valve installation and operation manual for mechanical installation. Instructions for wiring Liquid Controls valves to the Register can be found below.

 

Materials needed for wiring valves

These materials are necessary, but are not supplied with the valve:

16-22 AWG 4 conductor Shielded Cable (Consult the POD manual for complete specifications)

Weather Proof flexible conduit or loom

½” Conduit connectors or cable glands

PTFE tape or thread sealant

 

Disconnect Power

Disconnect the power before working on the CPU board.

 

Follow these steps to wire valves to the Register:

1.Attach cable glands and/or conduit connectors to the solenoid valve(s) and the Register port(s). Be sure to use thread sealant on NPT threads.

2.Thread the wires through piece of weatherproof conduit that is cut-to-length from the solenoid to a Register port.

3.Run the weatherproof conduit between the solenoid operated valve(s) and the Register housing, pull the wires through the ports, and tighten the connectors.

4.Connect the S1 solenoid-operated valve wires to terminals 23 and 24 on the J3 terminal block of the Register CPU board.

5.Connect the S2 solenoid-operated valve wires to terminals 17 and 18 on the J13 terminal block of the Register CPU board.

Earth Grounds for Solenoid Valves

The Earth grounds for Terminals 16 & 19 are optional. The solenoid operated valves are grounded through the component they are mounted on.

 

Follow this diagram as the guide to wiring a single stage valve for presetting:

Solenoid Operated Valve Cables

The 81527 solenoid operated valve (3-way LPG solenoid) has 3 cables potted into the housing. All other solenoid operated valves on Liquid Controls valves use cable assembly 81859, which has 2 cables.

 

Valves with 110VAC Solenoids

In order for the Register to control valves with solenoids on 110 VAC circuits, you must install a relay switch on the positive leg of the solenoid’s circuit.

 

Relay switch specifications

Switch: SPST (single pole, single throw)

Switch Position: Normally open

Contact Rating: Greater than maximum current of solenoid

Voltage: +12 VDC

 

Materials needed for wiring valves with 110 VAC solenoids

These materials are necessary, but are not supplied with the valve:

SPST relay switch (1 per solenoid)

20 AWG stranded wire (2 per solenoid)

Weatherproof flexible conduit, ½" diameter and ½" NPT conduit connectors or cable glands

PTFE tape or pipe sealant

 

To wire 110 VAC solenoids to the Register

Follow these steps:

 

1.Turn off all 110 VAC circuits before beginning the installation.

2.Install the specified relay switch(es) onto one leg of the 110 solenoid power supply circuit.

3.Connect the relay switch on the S1 power supply circuit to terminals 23 and 24 on block J3.

4.Connect the relay switch on the S2 power supply circuit to terminals 20 and 21 on block J3.

 

Disconnect Power (110VAC)

Turn off all 110VAC circuits before beginning the installation.
